' SPECIFICATION forming part of Letters Patent No. 761,37 '7, dated May 31, 1904. I

i Application filed March 19, 1903.

To all whom, it may concern:

Beit known that I, FRANK HAUsLE, a citizen of the United States, residing at NewYork, in the county of New York and State of New York, have invented a new and useful Adjustment and Fastening of an Opera-Chair Standard, of whichthe following is a specification.

My invention relates to improvements in adjustable opera-chair standards for theaters, public halls,assembly-rooms',&c. where chairs are to be built on riser-platforms; and theobjects of my improvementare, first,to provide to give the chair-standard no footing to the floor; second, to secure and fasten the chair-stand ard to the rear riser, and, third, that the adjustable holder of the chair-standard made it possible to fix any optional height of the seat and standard of the chair without consideration of the height of the riser in rear. I at.- tain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view of the adjustment, showing back part of chair-standard and the holder in position; Fig. 2, a top view of the holder; Fig. 3, a longitudinal section of the holder on the line 1 2,1'Fig. 2; Fig. 4:, a horizontal section of the T-rod of the back of the chair-standard on the line 3 l, Fig. 1. Fig. 5 is aperspective view of an adjustable operachair, showing the adjustment andfastening of the standard to a riser' in rear.

' Similar letters refer to similar parts throughout the several views.

-The T-shaped rod A, its support B, and the pinion O represent the adjustment. The teeth a of rod A in receiving those of rackC allow to fix the holder in certain height and hang the'chair-standard. The surface-lines band 0 (see Fig. 3) are parallel to give the standard a vertical position. The diagonal surface-lines (Z and a (see Fig. 3) show an opening to allow the entering and removing'of the holder. The screw-holes f are to fasten the holder to the riser.

I am not aware that prior to my invention an adjustable opera-chair standard in combi- Serial No. 148,649. (No model.)

nation with a holder securing the standard to the rear riser have been made.

What I do claim as my invention, and desire" to secure by Letters Patent, is

1. In combination with a chair-support provided with avertically-arranged rack,of a support therefor consisting of an upwardly-projecting portion having a Vertical wall toabut against the rear-wall of the rack, an inclined.

channel therethrou gh to allow the rack to slide freely therethrough, and a rack O formed below and opposed I to the upwardly-projecting portion adaptedto receive the first-mentioned;

ed to be secured to a platform and adjustably support the chair consisting of a casting havmg a casmg 1n the end for the reception of the rack of each chalr said casing being provided with an upwardly-extending shoulderadapted to receive the rear ends of each rack of the chair and a downwardly-extending rack to engage the rack of the chair and hold the same in adjusted position and an intermediate inclined channel of greater width than the horizontal space between the upwardly-extending shoulder and the downwardly-extending rack to allow free access of the racks of the chair through the casting whereby the chair-support can be moved upward and downward after having its upper end tilted forward thus disengaging the teeth of the vertical rack from the rack O allowing the support to slide freely through the inclined channel.

3. In combination with an adjustable operachair consisting of a seat and back, a support carrying arms and a vertically-arranged rack carried upon the rear portion of said support, of means secured upon a platform adapted to engage the rack and hold the same in an ad- PATENT I OFFICE. 1

justed position when vertical and to allow the same to be moved upward or downwardly when placed at an incline, said means being provided with a vertical rack adapted to engage the rack of the support when the same is in a vertical position and with an inclined channel above the rack through which is adapteii to slide the supports when placed at an inc me.

4. In combination with an adjustable operachair consisting of a seat and back, a support carrying arms and a vertically-arranged rack carried upon the rear portion of said support, of means for adjustably supporting the chair, consisting of two castings each of said castings having a casing in the free ends thereof provided with a centrally-arranged channel to allow the web of the rack of each chair to move therein, another channel in communication withthe first-mentioned channel, the centrally-arranged portion of which is of greater width and at an incline to the oppositely-extending portions of said channel, and a rack formed in the lower interior portion of said casing adapted to engage the racks of the opera-chair when the said racks of the operachair are at right angles to the casting whereby when the upper portion of the chair is tilted forward the racks are disengaged and the supports allowed to occupy the centrally-arranged inclined channel of the casting so that the supports may be readily moved upward or downward within the castings.

5. In combination with an adjustable operachair consisting of a seat and back, a support carrying arms and a vertically-arranged rack upon each side thereof, of means for adjusting and supporting the chair consisting of two castings each of which is provided with a casing in the free ends thereof provided with a centrally-arranged channel in the face thereof to allow the web of the rack of each support to move freely therethrough, an inclined channel formed intermediate of the casing inclining upward from the rear to the front and of greater depth than the rear wall of the upper portion of the casting, and a rack formed upon the front wall upon each side of the central channel but below the lower end of the inclined channel, whereby when each of the supports of the chair have their rear faces in engagement with the rear wall of the upper portion of the castings, the racks of the supports will be in engagement with the racks of the castings thereby holding the supports in an adjusted position, the upper portion of the supports being tilted forward disengaging the racks so that the supports can be readily slid within the inclined channel to accomplish the desired adjustment.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANK HAUSLE.
